PENGARUH MEDIA AIR LINDI TPA GUNUNG KUPANG DAN AIR LINDI TPA CAHAYA KENCANA TERHADAP LAJU KOROSI DAN JENIS KOROSI PLAT BAJA SPCC-SD JIS G3141

Abstract

Media studies to study the effect of different leachate media on corrosion rate and type of corrosion with variations of time 1 week and 2 weeks were removed, 2 weeks soaking and 1 week were removed, and 3 weeks soaking. The research data was obtained from the results of research with heavy methods and micro photographs. The successful variable is JIS G3141 spcc-sd steel plate, variable control is leachate from Gunung Kupang TPA and Cahaya Kencana TPA. From the results of the corrosion rate research obtained by leachate media taken from Mount Kupang landfill has the fastest corrosive properties the corrosion rate has an average of 0.718154 millimeters per year (mm / y) with soaking time of 2 weeks and 1 week removed. And the lowest corrosion rate at Cahaya Kencana TPA with an average corrosion rate of 0.131159 millimeters per year (mm / y) with a 3-week immersion time. The form of corrosion in the Gunung Kupang Landfill and Cahaya Kencana media is evenly corrosion.
